Trait TryFoldAll 

pub trait TryFoldAll<T>: Iterator<Item = T> + Sized {
    // Provided method
    fn try_fold_all<Acc, E: Error + From<Vec<E>>, F>(
        self,
        init: Acc,
        f: F,
    ) -> Result<Acc, E>
       where F: FnMut(Acc, T) -> (Acc, Option<E>) { ... }
}

Provided Methods

fn try_fold_all<Acc, E: Error + From<Vec<E>>, F>( self, init: Acc, f: F, ) -> Result<Acc, E>

where F: FnMut(Acc, T) -> (Acc, Option<E>),

Fold the results, returning the accumulated value if all succeeded, or packing all errors if any failed.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
